Bar College at Simon's Rock, also known as Simon's Rock and previously as Simon's Rock College of Bard (see below), is a small liberal arts college located in the small town of Great Barrington, Massachusetts, in the United States. The foremost of the many unusual things about Simon's Rock is that it is designed for students to enroll after completing the tenth or eleventh grade of high school, rather than after graduating. Students who attend Simon's Rock rarely earn a high school diploma, and enter, on average, at the age of 16.
